JOHN B. ROBERTS, OF WILKES-BARBIE, PENNSYLVANIA.

MINE-CAB PEDESTAL.

To all whom it may concern:

Be it known that 1, JOHN R. Rosnnrs, a citizen of the United States,residing at Wilkes-Barre, in the county of Luzerne and State ofPennsylvania, have invented a new and useful Improvement in Mine-CarPedcstals, of which the following is a specilication.

This invention relates to a mine car ped-,

estal, and the object of the invention is to improve the journal boxesused with mine cars, especially in the manner of introducing a lubricantto the bearings.

It has been customary to introduce oil through end openings and thencelead it to a point immediately above the shaft to be lubricated and tothen conduct it to said shaft by means of an opening "formed in abushing or hearing block.

My invention consists of a mine car pedestal in which the oil passagesopen upon the outer side of the pedestal and lead to an oil cup providedwith a bearing for the shaftor axle to be lubricated.

In the accompanying drawings Figure 1 is a side elevation of thepedestal. Fig. 2 is a section on the line 22 of Fig. 1. Fig. 3 is asection on the line 33 of Fig. 2. Fig. 4 is a section on the line 4.4lof Fig. 3.

In these drawings .1 represents a longitudinally grooved pedestal whichsu ports the timbers of a mine car as shown by dotted lines in Figs. land 3. This pedestal receives a slidable oil cup 9. which is providedwith a central bearing 3 for an axle 4c, and a bushing 5 fits over thesaid shaft, the shaft rotating in a ourna l box formed by the bearing 3upon the under side and the bushing 5 upon the upper side. It will beunderstood thatthe pedestal is transversely cut out in its lower centralportion to receive the slidable oil cup 2 with the bearing 3 and theaxle l and bushing 5. Upon opposite sides of said central cut outportion reservoirs 6 are formed in the pedestal and upon the outer faceof the pedestal are formed bosses 7 which bosses are provided with do nwardly inclined passages 7 which lead to the reservoirs 6. These bosses7 are curved Specification 02 Letters Patent.

so that their upper portions overhang the entrance to the passages 7thus protecting said passages from dirt and dust which otherwise mightfall into them. The reservoirs 6 open through passages 6 into the oilcup 2, thus feeding oil into said cup upon opposite sides of the axle 4.The sides of the bushing 5, it will be noted, form sides of thesaid-passages whereby the oil is' conducted to the cup around instead ofthrough said bushing. A suitable locking pin 8 preferably of springmetal is carried by a bracket 9 and locks the oil cup 2 and bearing 3 inlace.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is

1. In a device of the kind described a pedestal, a slidable oil cupcarried by said pedestal, said cup having a bearing for an axle, andbosses formed on a side ot the pedestal and upon opposite sides of theoil cup, said pedestal having reservoirs formed therein and beingprovided with passages leading through said bosses to said reservoirsand from said reservoirs to opposite sides of the oil cup, respectively,the bosses overhanging the entrance to the passages leading throughthem.

2. A mine car pedestal provided with in terior reservoirs, adjacent eachend, overhanging bosses formed on the outer face of said pedestal, oilpassages leading through said bosses to said reservoirs, the bossesoverhanging the outer end portions of said passages, an oil cup slidablyheld in the central lower portion of said pedestal, an axle'bearingformed in said oil cup, and a bushing for said axle, said pedestal beingprovided with passages leading from the reservoirs to opposite sides,respectively, of the oil on s, said passages being also upon opposite sies of the bushing, as and for the purpose set forth.

3. In a device of the kind described a pedestal, an oil cup having abearing formed therein for an axle, said cup being slidably held in saidpedestal, and a non-perforated bushing cooperating with said bearing toform a journal bearing for an axle, said ped- I ing forming,respectively one side of each of estal having interior reservoirs formedin said last mentioned passages.

the pedestal'and upon opposite sides of the JOHN R ROBERTS said bushing,means for introducing oil to i said reservoirs through the outer side ofthe pedestal, and passages leading from said res- I ervoirs to the oilcup, the sides of the bush- 1 I W itnesses:
